Write to spreadsheet file DBL no dialog pop up

[LeoYTL]

Hello, 

I encountered this issue when I was using "write to spreadsheet file DBL". There was never a dialog jumping up for manually choose a file path at the end of all the data acquisition. 

Does anyone else have the same problem ?

Tooltip says that a dialog box will pop up if the path is empty.  Is your path control empty? Use the Empty primitive in the comparison palette. 

[LeoYTL]

Yes, the file path is completely empty.

Did you use the Empy String/Path function like I suggested?  Both of the controls below appear to be empty but the first one is not.  Just trying to make doubly sure.

Yes ,I see the empty path control you mentioned but I don't know how to connect it with the "write to spreadsheet vi." I could not add anything in the block diagram in this sub-vi

I'm not sure why it is locked in your version.  It's not locked in mine but either way, you should not modify any of the VIs that ship with Labview.  You need to look at the file path that you are passing into this VI and check if it is empty.
